MOTOR-CASING- FOR TUBE-CLEANERS.

Specification of Letters Patent.

Application filed November 18, 1911. Serial No. 661,054.

To all whom it may concern:

Be it known that I, CHARLES MANTHEY, a citizen of the United States,residing at Stockett, in the county of Cascade and- State of Montana,have invented new and useful Improvements in Motor-Casings for Tube-Cleaners, of which the following is a specification.

The present invention relates to certain novel and useful improvementsin a device for cleaning or removing the scale from boiler tubes and hasparticularapplication to means whereby the scale as it is removed fromthe tube and dropped upon the body of the cleaner or hammer is blownfrom the latter by a charge of compressed air or steam, such as is usedto drive the hammer. By such an arrangement, I am enabled to keep thebody of the cleaner or hammer free from all deposits of soot or scale,thereby enabling the cleaner to more efliciently perform itsfunction'with the result that the tube will be thoroughly and rapidlycleaned.

Still another object of my invention is to so construct and arrange therear end of the body of the cleaner or hammer that a portion of thecompressed air or steam which drives the latter will be blowneoutagainst the outer surface of the hammer body from the rear toward thefront, thereby removing any deposits of scale which may have droppedupon or against the device.

With the above-recited objects, and others of a similar nature in viewthe invention consists in the construction, combination and arrangementof parts, set forth in and falling within the scope of the appendedclaims.

In the accompanying drawing :Figure 1 is a view partly in side elevationand 40 partly in vertical section, of a well-known and conventional formof tube scraper or scaling'hammer, and showin my invention Fig. 2 1s atransverse vertical sectional view taken through the as applied thereto;

rear end of the device. Fig. 3 is a rear end view with the collar nutremoved.

Referrin now to the accompanying drawingin detail, the letter Adesignates conven- 'tionally a motor casing of a scaling hammer of thewell known type wherein the scraper head l-is driven or operated by themotor within the casing A, the latter being. driven by steam orcompressed air. As the motor forms no part of the present invention, itis unnecessary to describe the same here in detail. 1

In the present instance, I form the rear end of the casing with agrooved flange 2 terminating in the stem 3 which is threaded exteriorlyas at 4, the interior of the stem Patented Mar. 4, 1913.

and the body of the casing being, of course,

tubular for the admission of the operating fluid. I drill into thecasing, beginning at vthe groove in the flange, a number of inclinedbores or channels 6, in the present instance four in number, these boresor channels opening communication between the interior of the casing andthe outer surface of the flange. Upon the threaded shank or stem I screwthe ring or collar nut- 7 which is provided with a flange 8 having thebeveled or tapered inner face 9, so that when the ring or collar isthreaded in place, the

beveled or tapered wall of the flange, which is thinnest at the extremeedge is desi ned to form a battle circuit for the air as it is blownthrough the channels or bores leadin to the flange 2, and thereby directthe fluid in small streams longitudinally of the body of the casing fromthe rear toward the forward end thereof. In the present instance, I haveshown the fluid pipe at B, by means of which the operating fluid isadmitted to the casing and it will be readily evident that as a portionof the charge entering the casing passes through the inclined channelsor bores, it will be directed forward along the exterior of the body ofthercasing and thoroughly clean the same by removing any depositthereon.

While I have herein mentioned my improvement as applied to a particulartype.

of tube cleaner, I wish it to be understood that the invention is notlimited to this specific application, as it is equall useful inconnection with other types of tu eyhammers ed to discharge a portion ofthe motive fluid from the casing, means connected to said casin fordirecting said motive fluid forward y of the outer surface of the casingsubsequent to the passage of the fluid through said passages.

2. motor casing for fluid actuated motors, said casing belng providedwith fluid conducting passages adjacent to one end thereof spaced apartand inclined rearwardly of the casing and adapted to direct a portion ofthe motive fluid rearwardiy of the casing and exteriorly thereof, andmeans surrounding the respective end of the casing adjacent to thepassages therein and adapted to direct the fluid issuing from saidpassages forwardly of \said casing on the exterior thereof. v

3. A motor casing for fluid actuated motors, said casing being providedwith inclined fluid conducting passages adjacent to one end thereof, agrooved shoulder on the casing at the outer extremities of said inclinedpassages and terminating in a reduced stem, and a ring on said stem and15 provided with a flange having a beveled and tapered inner facedisposed adjacent the groove in the flange at the outer ends of thefluid passages whereby the fluid discharged from said passages will bedirected for- 20 \vardly of the casingand around the same.

In testimony whereof I afiix my signature in presence of two witnesses.
